What changes will tadpoles experience when they grow up?

When tadpoles grow up, they will go through five processes: growing two hind legs-the tail becomes shorter-growing two front legs-the tail disappears-becoming a frog.

Early growth: tadpoles are not fed for 3 days after hatching, and rely on the nutrition brought by egg yolk to maintain their lives. Premature feeding can easily lead to their death. Pre-growth stage: After tadpoles hatch 10 days, their food intake increases, their growth and development accelerate, and they begin to look for new food. Mid-growth: At this time, the digestive function of tadpoles is constantly enhanced. Late growth period: this period is the key period for tadpoles to transform into young frogs, during which tadpoles will grow hind limbs and forelimbs.

Extended data

Tadpoles are the primary stage of amphibian individual development. Early tadpoles were round or oval, looked like fish and had lateral organs. Because there are no pores in the mouth, you can't eat; After that, eyes and nostrils appeared one after another; There is a sucker under the head, which can be used to adsorb on aquatic plants. There are external gills on both sides of the head, which have respiratory function.

The process of tadpoles developing into adults through metamorphosis is called metamorphosis. After tadpoles grow and develop, the metamorphosis time is greatly influenced by the breeding and hatching seasons and the external temperature. Generally, tadpoles that lay eggs and hatch in May-July can metamorphose in July-September, and tadpoles that breed and hatch after August-September can only metamorphose into young frogs after April of the following year.
